Installation and Start-up Guide 7 All rights reserved
WARNING Do not apply line voltage (mains voltage) to the router's ports and terminals.
CAUTIONS
• The i-Vu® XT Router is powered by a Class 2 power source. Take appropriate isolation measures when
mounting it in a control panel where non-Class 2 circuits are present.
• Carrier® controllers can share a power supply as long as you:
• Maintain the same polarity.
• Use the power supply only for Carrier® controllers.
To wire for power
1 Make sure the i-Vu® XT Router’s power switch is in the OFF position to prevent it from powering up before
you can verify the correct voltage.
2 Remove power from the power supply.
3 Pull the red screw terminal connector from the router's power terminals labeled 24 Vac/Vdc (+/-).
4 Connect the power supply's wires to the red screw terminal connector.
5 Connect an 18 AWG or larger wire from the power supply's negative (-) terminal to earth ground. This wire
must not exceed 12 in. (30.5 cm).
6 Apply power to the power supply.
7 Measure the voltage at the red screw terminal connector to verify that the voltage is within the operating
range of 20 to 30 Vac or 23.4 to 30 Vdc.
8 Insert the red screw terminal connector into the router's power terminals.
9 To verify the polarity of the wiring, measure the voltage from the negative terminal of the red screw terminal
connector to a nearby ground. The reading should be 0V.
10 Turn on the expander's power switch.
11 Verify that the LED on top of the router is on.
12 Measure the voltage at the red screw terminal connector to verify that the voltage is within the operating
range of 20 to 30 Vac or 23.4 to 30 Vdc.
